Res material

I'm currently creating a res which will have lots of corridors to go down to get to places. My question is: what should they be made of? I've included a picture of them with stone brick, but I feel that's overdone and could get repetitive. Just remember, I'm a person who needs to actually get these materials, too

Yeah, if you go to the strongholds on smp3 or somewhere else that was fairly unpopulated since the last waste reset, there's a fair amount of cracked and mossy brick.I only say smp3 from experience, no offense intended.

use some textural changes? make the corridors slightly wider and higher and experiment with stair and half blocks? it makes any journey more enjoyable as the roof isnt right in view

The corridors are that height for a reason. I don't have infinite space to mess with, so I need it kinda compact. The floor uses half blocks, and there's no space for stairs. This is a corridor, and I'm making it mildly interesting, not super-duper fancy.
